You're getting the toString() value returned by the Scanner object itself which is not what you want and not how you use a Scanner object. What you want instead is the data obtained by the Scanner object. For example,

Scanner input = new Scanner(System.in);
String data = input.nextLine();
System.out.println(data);

Please read the tutorial on how to use it as it will explain all.

Edit
Please look here: Scanner tutorial

Also have a look at the Scanner API which will explain some of the finer points of Scanner's methods and properties.

Learning java, need help understanding why I can't print this.

I just replicated your program in an abridged, minimal runnable version: https://ideone.com/OwIYvI And there, it runs without error. Contrary to what everybody else in this thread says, your program should run as my ideone from above proves. The suggestions to use a wrapper type are plain wrong as printf is absolutely supposed to work with primitives. My code that works on ideone: import java.util.*; import java.lang.*; import java.io.*; /* Name of the class has to be "Main" only if the class is public. */ class Ideone { public static void main (String[] args) throws java.lang.Exception { // your code goes here int ageYears, weightPounds, heartRate, timeMinutes; float avgCalorieBurn; ageYears = 49; weightPounds = 155; heartRate = 148; timeMinutes = 60; avgCalorieBurn = ((ageYears * 0.2757f) + (weightPounds * 0.03295f) + (heartRate * 1.0781f) - 75.4991f) * timeMinutes / 8.368f; System.out.printf("Calories: %.2f",avgCalorieBurn); } } The code is basically identical to yours, except for the naming.

[JAVA] Difference between creating a print method and using toString method?

In this line: System.out.println(bond) the println method calls the bond object's toString method to determine what to print. This is because the println method looks at the Agent class's toString method to determine how to make a String out of an Agent object. Because both Agent.toString and Agent.print create similar String objects, both method calls print the same information The difference is that you could store the String object returned by toString for later. Let's say you wanted to keep a description of bond for later: String description = bond.toString(); You could then reference description whenever you wanted, manipulate it, maybe save the description to a file somewhere, etc. The Agent.print method throws away the String that's made after printing, and creates a new one each time you call it, which is less memory- and CPU-efficient You could also make your code more maintainable by simply changing the print method to print like this: System.out.println(this); This would make println call the Agent.toString method, requiring you to only upkeep a single method More on reddit.com

Why does this code not print the Strings equal?: part

Please ensure that:

Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
You include any and all error messages in full
You ask clear questions
You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.
Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}
